This paper describes a new design method to obtain the inelastic deformation of pipelines induced by temporary ground deformations. The proposed design method consists of an elastic solution and a strain conversion procedure which was developed to predict the inelastic strain distribution by using the elastic solution and a stress-strain curve. Roundhouse type, yield-plateau type, and trilinear stress-strain curves are considered. Validation of the proposed method is conducted by comparing the results predicted by the proposed method with the results obtained by finite element analyses.
